Technical Specifications
This appendix provides the technical specification for the Cisco IE 4000 switches.
Operating Temperature Specifications
Table 3 on page 59 lists the operating temperatures for the Cisco IE 4000 switches in three different environments.

For example: NEMA4, NEMA4X,
NEMA12, NEMA13, IP54, and
IP66.
For example: NEMA1, IP20, and
IP21.
For example: NEMA TS-2.
Note: The minimum airflow is 150
lfm1.
1. lfm = linear feet per minute.
Note: The safety certifications apply only to ambient temperatures under 158°F (70°C). However, the
Cisco IE 4000 switch can function in the substation and traffic signal installations under the environmental conditions
shown in Table 3 on page 59.

-40C to +74C

-40C to +70C (Vented Enclosure Operating)

-40C to +60C (Sealed Enclosure Operating)

-34C to +74C (100LFM or more Fan or Blower equipped Enclosure
Operating)
-40C to +85C (Type Tested to +85C for 16 hours) 2
Note: If the unit is powered on at subzero temperatures it could take up to 12
minutes to complete the booting process. This is due to the internal heaters
that heat up the devices to safe operating temperature.
Operating humidity
5 to 95% (noncondensing)
Operating shock
30 g at 11 ms, and 200 g at 2.11 ms.
Operating altitude
Up to 13,000 ft (3962 m)
Storage altitude
Up to 40,000 ft (12,192 m)
Power Requirements
DC input voltage

Maximum operating range: 9.6 to 60 VDC

Nominal: 12, 24, or 48 VDC
Note:

The DC-input power supply is an SELV circuit, and it can only be
connected to another SELV circuit.

Input voltage for power supplies:

—
To power the switch, PWR-IE50W-AC-IEC and PWR-IE50W-AC
provide 24 VDC at 2.1 A.
—
To support PoE, power supplies PWR-IE65W-PC-AC and
PWR-IE65W-PC-DC provide 54 VDC at 1.2 A.
PoE mode vs PoE+ input voltages
—
PoE mode: 48 VDC (nominal)/44-57 VDC (absolute range)
—
PoE+ mode: 54 VDC (nominal)/50-57 VDC (absolute range)

1. Operating temperatures exceeding 60C are not covered by the product safety certifications and approvals. However, the
switch can function in the installations under the environmental conditions listed.
2. The maximum operating temperature of the switch varies depending on the type of SFP module that you use.
3. Power Consumption numbers are measured at 9.6V and do not include PoE power consumption
